| Test | What it does | Result |
|---|---|---|
test_pironio | The rate is Pironio et al. Eq. (12) term for term at unit gain, unit sifting and Shannon-limit reconciliation. | ✅ pass |
test_price | Along the depolarised-singlet line the CHSH term charges Eve as though the error were doubled, approaching the doubled binary entropy as the error vanishes and reaching 1.69 times the plain one at the threshold. | ✅ pass |
test_reconcile | A less efficient reconciliation lowers that threshold monotonically, reaching 6.394% at the photon-pair engine's own f = 1.22. | ✅ pass |
test_shared | The engine's Tsirelson bound is bit-identical to the photon-pair layer's. | ✅ pass |
test_threshold | The CHSH-priced rate vanishes at a 7.1% bit error rate against the photon-pair engine's 11%, which is what the state assumption was worth. | ✅ pass |
test_werner | The engine's error bridge inverts Acin et al.'s S = 2 sqrt(2) (1 - 2Q) exactly, and the violation is lost at a bit error rate of 14.645%. | ✅ pass |
